While the actor, Heathecote Williams, clearly can read, either he was a poor choice for this task, or the producers of this audio version had no experience with audio books. The production quality of this recording is terrible. I purchase a lot of audio books, but seldom have I had such a horrible listening experience.
The actor speaks in a droning monitone and then starts to yell in a high-pitched and squeaky voice.
I would suggest that you read this book rather than listen to this badly produced set of discs.
